Cutting Tips
1. When making long, straight cuts, it may be easier to use a
metal straight edge as a guide. Simply clamp it to the
workpiece to be cut. HTP America, Inc. also manufactures a
complete Circle-Cutting and Straight-Line Traversing
Assembly for frequent cutting of circles and lines.
2. When cutting heavier gauge material (up to the machine
capability) it is recommended to initiate the pilot arc off the
edge of the material and dragging the pilot arc to the
workpiece.
3. When making rust repairs, it is possible to place the new
metal over the rusted area and then cut your patch panel at
the same time you cut the rust. This process works similarly
when splicing a quarter panel.
4. Please note that sparks from cutting arcs can damage painted
surfaces. The sparks will also pit glass. We recommend the
use of a welding blanket to protect these surfaces.
5. The best cutting speed is achieved when the plasma arc
penetrates the workpiece at an angle of 5-15 degrees. The
cutting speed is dependent on material thickness and
composition as well as operator proficiency.
6. Never turn the machine off immediately after cutting.
Always allow the post airflow circuitry to run its complete
cycle to ensure proper cooling of the torch head.
7. It is highly recommended that piercing requirements be kept
to a maximum of 75% of rated cutting thickness. This will
greatly enhance the plasma torch's consumable life. When
piercing thick pieces of metal, it is best to hold the cutting
torch at a 45-degree angle to the work until the plasma arc
has pierced the material. Holding the torch perpendicular to
the work will result in sparks and slag firing back up into the
plasma torch, greatly reducing consumable life.
